Also keep this in mind: Ambient air temperature wasn't affected, but the hotter surfaces will continue to radiate heat into the cabin after you've gotten into your car and started running your a/c. It'll be easier to cool the car with the surface that is less hot.

This seems like common knowledge but I'm glad you conducted this experiment. Having the data to back it up is a beautiful thing. Well done.

I always use sunshades on my windshield because it takes less time to cool the car when you are not trying to overcome those extreme surface temps.

You should always use a sunshade if you don’t have a garage. The UV light will make your dash and leather crack and discolor.

These shades, in conjunction with quality window tint. have been proven to work. I live in South Texas and its mid summer right now. I bought a 2010 Chevy Malibu and going to lunch at 12pm is no joke with this heat. My car was about 150 degrees inside, with it being about 99 degrees outside. I added the solar shade and now my temp was at about 110 degrees inside, with it being 100 degrees outside. HUGE difference, and the life of my dashboard will be extended drastically. Best 10 dollar investment so far for my car

johnny5's Vids True but the windows closed do help keep sun out especially if they are tinted. All you gotta do is when you get in roll windows down blast the air not the AC just the air circulation then after couple minutes turn in the AC if you like. What you are trying to do is circulate the air at first then you can cool it with the AC

That's what she said

People forget the true purpose of sunshades is not to keep ambient temperatures down, but to reduce the surface heat of the dashboard, steering wheel, and other interior- thus prolonging the life of those areas from cracks, fading, and other sun damage.

I was just Googling to find this out and your video came up. Thanks!

Thanks for running the test. Appreciate the insight

Great experiment. Thanks for taking the time to record video.

Excellent, short and giving all necessary info.

Great test, I was wondering this myself for quite some time.

Nice test! I like the approach you used.

Thanks for the demo!

I feel like you should have done this with a third car that has a sun shade made of any other material like cardboard or something. That way we can see if any other thing blocking the sun would give the same results as those reflective shades.

great video , short and to the point

Thank you very much. This confirms what I have experienced.

I think a full test would include how long those vehicles take to cool after the vehicle is started. If sun visors reduce surface temperatures (which you have proven) those surfaces aren't radiating heat, which your AC system has to remove. Air has a low mass, so it's easier to cool than the surfaces in your car, which can retain much higher heat energy due to their relatively higher mass than air. Additionally, air is circulated, which cools it faster than objects in your car, which trap heat under the surface. Those objects release heat slowly as the heat is removed on the outermost layer and heat moves slowly outward from the inner layers.

Great video thanks I needed this information for a project

I'd like to see an experiment done with these put on the outside of windshield. Stop the heat BEFORE it gets in.

Great job, thanks!

Amazing...Thanks for going to the trouble of conducting a test so others can benefit :) Can you please do one using the nylon sun shades that are rolled onto the backseat windows?

I agree the sunshade is really more about protecting your interior than lowering air temp.. The main reason regardless of side window tinted or not and why the air temp was the same was the shade is inside the car. The heat has already made it inside the car at that point. Now if you had put the shade on the outside of the window it probably would have made a difference in "air" temp because its reflecting the heat "before" it reaches the inside of the car. However, with no side or rear protection it will only go so far. If you want to block "heat" the protection needs to be outside.

Awesome video

really curious to see how having windows opened affects everything

Many late model cars have UV blocking windshields. For example, the 2010+ Gen III Prius has UV glass in the windshield location. It reduces the heat and UV transmitted to the cabin.

@CaptainCocaine

UV only accounts for a very small amount of the thermal radiation entering a vehicle. Unless you have a broad-spectrum ceramic tint on your windshield which can block UV *and* infrared radiation, there will still be plenty of heat radiating into the vehicle through the windshield.

Try a weathertech shade. They're insulated and highly reflective.

I have one cause none of my windows are tinted I just keep it in the back seat when it’s hot out or I know cars going to be sitting for awhyll I throw mine up on the front window. Mines a little big but it works the centre mirror and the sun visors help hold it up. It’s not a 100% perfect fit but it dose help keep the car cool and helps keep the dash from getting destroyed by the sun. So no cracked or warped dashes I like mine it was cheap but gets the job done and only takes 2 seconds to put up

Very helpful bro

Now you need to do a test of how fast the Cars cool down from that state, so turn them both back on removing the sun shade from both and seeing if the car that's serfaces are at a lower temp decrease the amount of time it takes for the car to reach Maximum Cold.

Definitely works to drop the temp when combined with good UV blocking tinting on the other windows. I use mine since the new car has all of these electronics now....heads up display and pop up nav along with trying to preserve the wheel and the dash itself from UV damage.

Why were the compass readings almost 180 degrees apart when placed at the same location in each car?

Thanks for posting. I'm trying to figure out if it's worth getting the customized Weathertech sun shade or not--it's roughly 50 bucks. Kraco sun shades are a fraction of the price, at 13 bucks. Based on these findings, the science says that there really isn't all that much of difference between the two in terms of temperature changes.

a sunshade and ceramic window tint together make a huge difference

An importance of keeping the dashboard cooler is that the schmutz on the interior of the windshield is due to the plastic particles that melt in high heat and become airborne and stick to the glass

Does anyone else notice that after your car has been sitting a while, that the thermometers for the exterior and interior are alot usually hotter than the actual temperature? I think it may have to do with where they are positioned. I am pretty sure some cars temperature sensors are mounted inside the rear view mirror. If that's the case you wont get an accurate measurement unless you drive around and let the surfaces cool

Also helps when windows are tinted. I live in South Florida and always use a sun shade. I rarely see other people using them--I don't get it.

Neat, I always thought it was a placebo effect people used because they thought it made their cars cooler. Nice to see hard numbers disprove that

It comes in handy when you're in a quick run and you stirring wheel is not burning!

The windshild blocks most uva and uvb this is why when people get EXPENSIVE transition lenses in their glasses and the sales person doesn't tell them they won't work while driving they come back extremely mad, photocromic lenses are needed for driving

I usually throw it on when the car is cool inside and it’s going to sit in the sun ☀️ for a while when I get back in the car is cool but I live in southern Cali doesn’t get to 111 degrees in my area 😀

Now get ceramic tint on all window's, plus use complete cover sunscreens on all windows...that's what I do, keeps it nice and cool.

i got one for free so its whatever to me but i use it on a regular for the fact that it keeps the direct sunlight off any electronics in the front of the car plus with the windows cracked it helps quite a bit compared to nothing at all. either way when it gets really hot there is no way around the fact that the cab is gonna be lit especially when you have a black paint job like i do or these cars. even with all the windows blocked off its gonna get toasty.

They don't reduce the heat that much but they will stop fading and cracking of car interiors.

With more hours, the unshaded air temp would have gotten 20+ degrees hotter. Especially if you crack the windows on the shaded car too.

ya...next time I would try using the newer "white" exterior color offered on sunshades compared with the Silver....

you forgot to messure the seat belt.... that thing is like melting ( normally is 130FH outside and inside my car feels like 200 lol)

170 and 120 temp is just the same hot. anything above 100. i hope some can bring it down to below 100. i really think if the sun shade material is place outside the windshield it will reduce the temp better.

The problem isn’t uv. Glass doesn’t block infrared heat. And the side windows don’t block uva which still causes skin damage.

You should try it with a Weathertech full sunshade kit or cut sunshades for all the windows out of reflectix and do the experiment again

Direct sun definitely reduces suns damaging UV, which can destroy your dashboard!

You should put shades on all windows it'll reduce air tempter significantly

that sucks,i thought it would AT LEAST lower the temperature of the air temperature a littlw bit. That's why I have one. It's nice that it reduces surface temperature though.

how about if u add door window sunshade ?

i drive a suv and it came with the back windows already dark, just the front ones dont have a tint or nothing, i use a windshield sun shade for my dash and just hang them sun screens on driver and passanger the difference is really noticeable. and even before i tint them it was still noticeable the back was considerable cooler than the front, you wouldnt burn your ass, arms and back. with the whole windows some what blocking the sun reduced the tempeture to few ° above the tempeture outside the vehicle. its worth doing it.

The sunshade with window tent would greatly reduce the temperatures

Surprised by the air temp.

What part of the country do you live in?

I would love to see this tested for convertibles

I have ir ceramic tint on rear and side glass put up a sun shade and leavd the sunroof in thd vent position and my car stays zbout 75 inside 0n days its 100°

it works better not in the middle of the day.. if the car is towards sun in the afternoon shied really works..

Tint the windows on the test car then redo the test. Using a sun shade on one window does not keep the heat, sun, and UV rays from entering the other widows. Should have thought about that before the test.

You need to have two exactly identical cars to really pull this test off. There are to many variables in this one.

Windows tinted , and a sunshade make a drastic difference.

Starts at 2:14

111 is far from “toasty.” Lolll

Kind of a no-brainer. On a hot day the difference between getting into a car with a windshield shade Vs a car without one is pretty dramatic.

111 is hot! Hope that's dry heat =)

A sun shade is pointless with a car without at least the standard/factory window tint on the driver and passenger sides.

The control car being a full generation newer definitely affects the outcome of this test. I think the temp differences on the surfaces would have yielded similar results, but I'm not convinced that the air temp would be exactly the same.

okay, here's my question, why would you have these vehicles already in the heat before putting the visor up? a typical user would have had the AC running before putting the visor up. so I think your test is totally inconclusive in regards to ambient temperature after putting up the visor.
